SPECIFICATION forming part of Letters Patent NO. 477,993, dated June 28,1892.

' Application filed March 12, 1892?- To all whom it may concern.-

Be it known that we, JOSEPH CONLEY and- JAMES M. WOLFE, citizens of the United States of America, residing at Tarkio, in the county of Atchison and State of Missouri, have invented certain new and useful Improvements 1n Brick-Kilns; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable :0 others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in brick furnaces or kilns.

The object of the invention is to provide a furnace or kiln of improved construction for burning bricks after they have been clamped or dried, said furnace or kiln being provided with means for regulating the supply of hot or cold air to the bricks and feeding fuel to diflerent parts of the kiln, asmay be needed, as will be hereinafter fully set forth, and particularly pointed out in the claims.

By our improved construction we provide a kiln for burning bricks which will have but a single chimney at one end and openings at the opposite end for starting the fire, while at 0 intermediate points are fines for admitting air to the interior of the kiln, said flues having dampers for closing communication between the same and the furnace.

In the accompanying drawings, forming part of this specification, Figure 1 is aground plan showing one form of kiln with single center flue constructed in accordance with our invention. Fig. 2 is a vertical longitudinal section on the line a: m of Fig. 1. Fig. 3 is a ground plan of a modification showing the flues arranged at the side of the kiln; Fig. 4 4 is a longitudinal section on the'line y y, Fig. 3. Fig. 5 is sectional View on the line 2 ,2, Fig. 1. Fig. 6 is-a sectional view on the line to w of Fig. 3. Fig. 7 is a'view showing the manner of stacking the bricks in forming the fuel-chambers.

A designates the end wall of the furnace or kiln, which is provided with an ash-pit a, having suitable doors, and above the same gratebars a.

Immediately in the rear of the doorway a Serial No, 424,714. (No model.)

? are arches of the same width as said doorways, but of greater height.

The side walls B B of the kiln are intersected transversely below 'the'ground level with flues D,'which are provided at suitable intervals with apertures d, (shown in Figs; 5 and 6,) over which move dampers d, operated by rods, which extend into recesses 6, formed in the side walls above theflues.

Between each of the cold-air lines or ducts are arranged flues, which connect with the chimney F, said hot-air flues E having similar dampers to those arranged over cold-air flu es. The hot-air fines in the plan shown in Fig. l are all connected with the central' flue E, which leads directlyinto the chimney F. The side walls are provided at suitable intervals with-arched doorways B, through which the attendant can pass and carry the dried bricks and properly stack them within the'kiln.

Adjacent to each doorway and within the kiln is a paper partition, with board 6', 10-

dried bricks to form a clamp are stacked in each section, as shown in Fig. 7 of the drawings, so as to provide a multiplicity of vertical spaces is, extending from the floor of the kiln to the top .thereof, some of the bricks projecting into said spaces to provide ledges upon which a certain amount of fuel may lodge, the straight portions of the spaces registering with the damper-openings of the hotair fines. The dampers cl of the cold-air dues are midway between the spaces, as shown in Fig. 7. The bricks are stacked, so that the hot air can circulate amonglthem. When the bricks have been stacked to near the top of the kiln, the last two layers are placed close together the fiat way of the brick andclay placed thereon to cover any openings and provide a tight top, with the exception'of the openings leading from the vertical spaces It, said openings being closed by potsl, having flanges which support the same. These pots are simply to feed fuel through to the fires at the lower portion of the kiln and upon the projecting bricks after the furnace, where fire is started, has been closed. 7

In operation after the dried bricks have been placed in the kiln the fire is started upon the grate-bars a, the doors leading thereto being left open and the fuel-pots I closed, while the dampers of the hot-air flues adjacent to said grate-bars are left open, so that the products of combustion can pass to the chimney. The fire is continued until the bricks are sufficiently water-smoked. The heat acting on the lower bricks first, dries them and prevents crushing. After the bricks in the first compartment are water-smoked the dampers over the first hot-air fines are closed and the board 6 withdrawn, thus connecting the first section with the second section of the kiln to water-smoke the bricks in said second section, and so on throughout the kiln. By the time the bricks in the second chamber or compartment have been water-smoked the fires of the kiln can be fed from the fuel-pots over the first section, and when said fuel is fed and ignited the doors in front of the ashpit and the doors a are closed and air admitted through flue D to supply the products of combustion, these air-fines giving the necessary draft and, being provided with (lampers, the intensity of the heat can be varied. If the attendant sees at any time that the bottom of the kiln is becoming heated too much in advance of the top, the dampers can be closed either in bottom of kiln or in neck of stack.

The partitions c, hereinbefore referred to, may be made of paper or equivalent substance.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In abrick-kiln, the combination of a furnace having grate-bars at one end and a chimney at the other, transverse partitions ex tending from one of the longitudinal side walls to the other for dividing the kiln temporarily into sections, each section having underground transverse induction and eduction. fines connected to the chimney, said transverse flues having openings in their upper portions, and transverse dampers adapted to be operated from without the side walls, substantially as shown, and for the purpose set forth. v

2. In a brick-burning furnace or kiln, the combination of a rectangular structure having at one end a starting-furnace and at the opposite end a chimney, a longitudinal underground fiue connected with the chimney, a series of underground transverse fiues opening through the side walls and communicating with the interior of the kiln to admit cold air thereto, intermediate underground hot-air flues connecting with the longitudinal flue,

which communicates with the chimney, the transverse fines having dampers, and removable partitions for separating the body of the kiln into sections, substantially as shown, and for the purpose set forth.

3. In combinationwith a brick-burning furnace constructed substantially as shown,

having a furnace at one end, with grate-bars and a chimney at the other, which connects with central and laterally-extending underground fiues, air-supply flues arranged alter-- nately with the transverse flues connected with the chimney, and fuel-feeding receptacles supported by the top of the kiln, substantially as shown, and for the purpose set forth.

4:. The combination, with a furnace or kiln constructed substantially as shown and adapted to be separated by transverse partitions, of a removable board e, forminga part of each of the partitions, transverse underground flues below the removable board, and a furnace located at the opposite end of the structure from the chimney, substantially as shown, and for the purpose set forth.

In testimony whereof We aflix our signatures in presence of two witnesses.
